摘要:
A pressurized spray system. The spray system has a flow path through which contents must pass to be dispensed from the system to the atmosphere. By maintaining the proper proportions of restrictions in the flow path to the spray nozzle exit orifice, a relatively constant mean particle size distribution may be obtained throughout the life of the spray system as the pressure decays.

A device for treating a target, such as cleaning a window. The device has a handle and head, mounted in pivotal relationship to each other. When the head is placed in sliding, contacting relationship with the target surface the handle can pivot relative to the head for the ergonomic convenience of the user.

摘要:
A device for treating a target surface, such as occurs when cleaning a window. The device has plural squeegee blades joined by a head. The head has a slot therethrough. A sheet may be longitudinally move over one or more than one of the blades to renew its surface before, during or after use. Each squeegee blade may have a dedicated sheet. The sheet(s) may travel through the slot to originate from or be stored within the head.

摘要:
A device for treating a target surface, such as occurs when cleaning a window. The device has a squeegee blade or other member to apply pressure to the target surface. A sheet movably covers the blade, to present a fresh covering to the target surface with each use. The fresh surface provides for improved removal of the liquid from, or improved treatment of the liquid on, the target surface. Additionally or alternatively, the sheet may comprise a prewetted substrate to apply the liquid to the target surface.
摘要:
An apparatus for removing debris from a target surface. The apparatus comprises a hollow roller with a supply roll and take-up roll axially rotatably disposed within the volume of the hollow roller. A sheet material, such as adhesive tape, extends from the supply roll through a slot, around the periphery of the roller at least 180°, back into the slot and onto be take-up roll. A partition separates the supply roll and take-up roll, reducing contamination of tape on the supply roll. An index mechanism may be provided to advance the tape one path length from the supply roll to take-up roll, the user does not overuse or underuse fresh tape.
摘要:
A cleaning implement comprising a multiply re-usable device and a disposable refill. The device has a handle for grasping by a user and a white attachment portion, for removable attachment of the refill. The device is substantially a first color having a first hue and the refill is substantially the same first color and has a second hue of the same first color
